Hi! This is NOT a NetBSD bug, but I'm really curious as to whether anyone's
This program reliably hangs three different AMD64 machines, all of them
Athlons, and all with nForce4 chipsets. I would love to know more cases
where it works or doesn't. Hangs have been observed under 64-bit Linux
and 32-bit Windows.
unsigned char a[4*1024*1024];
memset(a, 0, 4*1024*1024);
This program 100% reliably hangs my Athlon64 box. It takes under 10 seconds
under Linux, several minutes on Windows. And no, that doesn't make any sense.
I don't have any EM64T boxes handy for testing.
